Spinning of thin metal plate with diode laser

Abstract

Spinning with diode laser is newly proposed and experiments on AISI304, magnesium and titanium alloy plates are carried out. The sizes of the plates are 0.3, 0.4 and 0.5mm in thickness and 70 mm in diameter. The laser is scanned on lines of 1, 2, and 3mm away from the circumference. An AISI304 plate of 0.3mm thick can be formed into a shape of head of vessel of the diameter of 66mm, and a height of 2.0mm. The bending angle is about 90 degrees. Titanium alloy plates are difficult to form. Magnesium alloy plates are easy to form; however, the surface layer occurs to melt.
